Error Loading Cluster Data

Hi,

I clicked on Kopt, Head, and Migration from dashboard for production deployment and those are unable to load cluster data. I believe these used to work before. How can I correct this problem? The error log I see in one of the plugin is following:

[2016-09-13 12:05:18] Elasticseach connection:
[2016-09-13 12:05:18] {"host":"https://cd2a43ca6e2a523177795af9b5e27c8a.us-east-1.aws.found.io:9243","withCredentials":false}
[2016-09-13 12:05:18] Error requesting cluster data:
[2016-09-13 12:05:18] {"data":{"error":"IndexMissingException[[_all] missing]","status":404},"status":404,"config":{"method":"GET","transformRequest":[null],"transformResponse":[null],"url":"https://cd2a43ca6e2a523177795af9b5e27c8a.us-east-1.aws.found.io:9243/_stats/docs,store","headers":{"Accept":"application/json, text/plain, /"}},"statusText":"Not Found"}

Actually, I found out why.

It was due to logging in with a shield account without the access rights.
